[bug#54892] [PATCH] gnu: nomad-optimizer: Fix some tests.

["Paul A. Patience" <paul@apatience.com>]

* gnu/packages/maths.scm (nomad-optimizer)[arguments]<#:phases>
[fix-sources-for-tests]: Enable the pipefail option in the (generated)
script that runs tests. Enable the basic batch example3 test. Fix the
advanced library FixedVariable test (and seemingly the neighbor PSDMads
test). Expand some comments.
---
To be applied after the patch updating nomad-optimizer to 4.2.0.
